Paperwork — it’s what makes the business world go ’round. But now that most organizations have undergone digital transformations, we’re finding more companies using digital signature software.

Maybe you’re thinking of doing the same?

Whether you’re looking for the best electronic signature software for personal or business use, we’ve got the tools for you.

Let’s check them out.

It’s a document management platform that focuses on sales (although it does have an e-signature feature with the capacity to collect all types of e-signatures). It’s a valuable asset for enterprises since it incorporates a wide variety of templates specific to the sales cycle, such as sales quotes, proposals, and contracts.

If you’re like most, you prefer to send and receive PDF documents for signatures. In this case, you need a PDF editor.

PDFfiller is the best electronic signature software for this purpose. It’s GDPR compliant, and it’s accessible online (in other words, no need to download any software).

How to Decide on Electronic Signature Tools

The tools described above all have one thing in common: they allow secure digital signing of digital documents. However, deciding on one over the other will depend on your circumstances. Below is a step by step process for selecting the best electronic signature software for your needs.

Step 1 – Consider your needs

The main purpose of these tools is to allow you to provide or collect a legally-binding digital signature on a document. The first thing to consider is the number of documents you’ll need to digitally sign monthly.

If you have to sign two or three documents a month, then free options are a better choice. You can use DocuSign Free Edition or the free version of HelloSign.

If you send out many documents to collect signatures, the free version of PandaDoc can come in handy. However, if you need to create documents or access templates, a paid version of these tools might be more appropriate.

You also need to consider at this point how much security you need for your transactions. While all these tools use security technology to protect its users, they’re not all on the level of OneSpan Sign. But if you simply want to track and audit your documents, HelloSign might be more your speed.


  • Send only: Free versions of Docusign and HelloSign
  • Create, send and collect: Paid versions of PDFfiller, SignNow, PandaDoc, Adobe Sign, Docusign,HelloSign
  • High-security create, send, and collect: OneSpan Sign

Step 2 – Consider the number of users

The next step is to consider the number of people that’ll use the software. In a small business, it’s common for one person to handle all the sending of documents for signing.

In this case, you want to choose a tool priced the lowest per user, such as Docusign, PDFfiller, or HelloSign.

On the other hand, a larger business with multiple users can get the most bang for your buck with Adobe Sign, which allows up to 9 users for $20.99 a month. The only exception is if you’re managing a sales team — in this case, you might have to bite the bullet with a paid plan on PandaDoc.


  • Single user: PDFfiller, SignNow, PandaDoc, Docusign, HelloSign, OneSpan Sign
  • Multiple users: Adobe Sign

Step 3 – Consider integration

Choosing an e-signature tool for personal use allows you to choose any of the software discussed in this article. But if you need one that integrates with business tools you’re using, you’ll need to pick more carefully.

The good news — most of these tools integrate with major platforms, such as Microsoft, Salesforce, Google Drive, and Dropbox. If you’re using CRM, payment, and storage platforms, you need to check if the tool you’re eyeing can integrate with them.


  • Personal use: PDFfiller, SignNow, PandaDoc, Adobe Sign, Docusign, HelloSign, OneSpan Sign
  • Business use: Check for integration with third-party apps

Step 4 – Consider ease of use

The last consideration for choosing the best electronic signature software is the ease of use. The tools discussed above have varying levels of intuitiveness, and those that have a bit of a learning curve is primarily due to the e-signature feature being a part of a bigger platform. This is true in the cases of PandaDoc , Docusign, and Adobe Sign, which are actually document management suites.

On the other hand, tools that are primarily e-signature software are easier to use, but with limited document management capabilities. If you simply need a tool to send and collect e-signatures, then PDFfiller, SignNow, HelloSign, or OneSpan Sign will fit the bill nicely.


  • Easy to use: PDFfiller, SignNow, HelloSign, OneSpan Sign
  • Not so easy to use: PandaDoc, Docusign, and Adobe Sign
